EVERY household in Britain is £445 poorer because of Tony Blair’s disastrous renegotiation of the EU rebate.

Tony Blair’s rebate fiasco, which has cost each household in Britain £445, is revealed[PA]

The true cost of the former Labour prime minister’s blunder was exposed yesterday with some £10billion lost over the past five years.

Mr Blair agreed in 2005 to future reductions in the rebate – which were hard won by the late Baroness Margaret Thatcher in 1984.

He made the concession in return for reforms including the scaling back of farming subsidies under the Common Agricultural Policy, which failed to materialise.

The price Britons paid was shown in figures obtained by Eurosceptic pressure group, Business for Britain, using Freedom of Information laws, ahead of next month’s 30th anniversary of the Fontainebleau summit at which Baroness Thatcher won the rebate.

The reductions Blair agreed were phased in from 2008.

The total rebate paid up to last year was £10.4billion less than it would have been without his deal.

Last year, under the agreement Baroness Thatcher negotiated, the rebate would have returned £6.1billion to Britain instead of the £3.3billion it is estimated to be.

This shows how much Labour cost taxpayers... how Blair was prepared to strut around on the international stage

MP Philip Davies

That represents a 45.5 per cent loss of value.

The rebate has averaged £3.1billion over the past four years while farming subsidies still eat up 38 per cent of the EU budget.

In a warning to Prime Minister David Cameron, who plans to renegotiate Britain’s EU terms, Business for Britain chief Matthew Elliott said: “The extent to which our rebate was thrown away for empty promises of agricultural reform is breathtaking.”

Leading Eurosceptic Conservative MP Philip Davies said: “This shows how much Labour cost taxpayers... how Blair was prepared to strut around on the international stage, and how the rebate which was so hard-won was so easily given away.”

He told the BBC: “It’s a sort of elevated form of petulance to say ‘We’re going to stamp our little feet to get our little short shopping list of really rather minor changes...and if we don’t get them we’ll quit’.
